> 1. Years ago a traffic engineer proposed a new way to keep pedestrians safe from auto traffic, and autos from other autos. He wanted traffic lights to operate in a three-phase cycle: in phase one, pedestrians would not move, and only north-south auto traffic would move; in phase two, pedestrians would not move, and only east-west auto traffic would move; in phase three, no autos would move, and pedestrians could move in any direction they pleased, including diagonally. I believe this idea was tried in San Francisco, but obviously not adopted. I wonder what problem was found to prevent its adoption; it looks promising to me. When I first asked this question years ago, no one gave me any good answers; the only one I recall is that someone said that people couldn't get the hang of it. What I'm hoping for is a pointer to some authoritative report.
